RELATED APPLICATION
BACKGROUND
[0002] Methylation of protein lysine residues is an important signaling mechanism in eukaryotic
cells, and the methylation state of histone lysines encodes signals that are recognized
by a multitude of proteins and protein complexes in the context of epigenetic gene
regulation.
[0003] Histone methylation is catalyzed by histone methyltransferases (HMTs), and HMTs have
been implicated in various human diseases. HMTs can play a role in either activating
or repressing gene expression, and certain HMTs (e.g., euchromatic histone-lysine
N-methyltransferase 2 or EHMT2, also called G9a) may methylate many nonhistone proteins,
such as tumor suppressor proteins (
see, e.g., Liu et αl., Journal of Medicinal Chemistry 56:8931-8942, 2013 and
Krivega et αl., Blood 126(5):665-672, 2015).
[0004] Two related HMTs, EHMT1 and EHMT2, are overexpressed or play a role in diseases and
disorders such as sickle cell anemia (
see, e.g., Renneville et αl., Blood 126(16): 1930-1939, 2015) and proliferative disorders (
e.g., cancers), and other blood disorders.

DETAILED DESCRIPTION
[0040] The present disclosure provides novel amine-substituted heterocyclic compounds, synthetic
methods for making the compounds, pharmaceutical compositions containing them and
various uses of the compounds.
[0041] In one aspect, the compounds disclosed herein may be used to treat a blood disorder,
e.g., sickle-cell anemia (i.e., sickle-cell disease). Non-limiting examples of sickle-cell
anemia forms that may be treated using the contemplated compounds include hemoglobin
SS disease, hemoglobin SC disease, hemoglobin Sβ
0 thalassemia disease, hemoglobin Sβ
+ thalassemia disease, hemoglobin SD disease, and hemoglobin SE disease.
[0042] Without wishing to be bound by any theory, it is believed that sickle-cell anemia
describes a group of inherited red blood cell disorders in which at least some of
the red blood cells of a subject having sickle-cell anemia contain hemoglobin S ("HbS").
Hemoglobin S is a mutated, abnormal form of adult hemoglobin. Without wishing to be
bound by any theory, it is believed that the contemplated compounds may treat sickle
cell anemia by inducing fetal hemoglobin ("HbF") expression.
See, e.g., Renneville et αl., Blood 126(16): 1930-1939, 2015, the content of which is incorporated herein by reference in its entirety.
[0043] In some embodiments, one or more complications of sickle-cell anemia may be treated
or prevented using the contemplated compounds disclosed herein. Non-limiting examples
of complications that may be treated or prevented using the contemplated compounds
include anemia (e.g., severe anemia), hand-foot syndrome, splenic sequestration, delayed
developmental growth, eye disorders (e.g., vision loss caused by, e.g., blockages
in blood vessels supplying the eyes), skin ulcers (e.g., leg ulcers), heart disease,

carbon atoms. In one embodiment, bridge rings are one or two carbon atoms. It is noted
that a bridge always converts a monocyclic ring into a tricyclic ring. When a ring
is bridged, the substituents recited for the ring may also be present on the bridge.

[0215] The term "substituted," as used herein, means that any one or more hydrogen atoms
on the designated atom is replaced with a selection from the indicated groups, provided
that the designated atom's normal valency is not exceeded, and that the substitution
results in a stable compound. When a substituent is oxo or keto (
i.e., =O), then 2 hydrogen atoms on the atom are replaced. Keto substituents are not present
on aromatic moieties. Ring double bonds, as used herein, are double bonds that are
formed between two adjacent ring atoms (
e.g., C=C, C=N or N=N). "Stable compound" and "stable structure" are meant to indicate
a compound that is sufficiently robust to survive isolation to a useful degree of
purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
[0216] The term "optionally substituted," as used herein, means not being substituted (e.g.,
none of the one or more hydrogen atoms on the designated variable is replaced with
any other group) or being substituted (e.g., any one or more hydrogen atoms on the
designated variable is replaced with a selection from the indicated groups, provided
that the designated atom's normal valency is not exceeded, and that the substitution
results in a stable compound).
[0217] When a bond to a substituent is shown to cross a bond connecting two atoms in a ring,
then such substituent may be bonded to any atom in the ring. When a substituent is
listed without indicating the atom via which such substituent is bonded to the rest
of the compound of a given formula, then such substituent may be bonded via any atom
in such formula. Combinations of substituents and/or variables are permissible, but
only if such combinations result in stable compounds.
[0218] When any variable (
e.g., R) occurs more than one time in any constituent or formula for a compound, its definition
at each occurrence is independent of its definition at every other occurrence. Thus,
in some embodiments, if a group is shown to be substituted with 0-2 R moieties, then
the group may optionally be substituted with up to two R moieties and R at each occurrence
is selected independently from the definition of R. Also, combinations of substituents
and/or variables are permissible, but only if such combinations result in stable compounds.

shown and claimed nitrogen-containing compounds are considered, when allowed by valency
and structure, to include both the compound as shown and its N-oxide derivative (which
can be designated as N→O or N
+-O
-). Furthermore, in other instances, the nitrogens in the compounds of the present
disclosure can be converted to N-hydroxy or N-alkoxy compounds. In some embodiments,
N-hydroxy compounds can be prepared by oxidation of the parent amine by an oxidizing
agent such as m-CPBA. All shown and claimed nitrogen-containing compounds are also
considered, when allowed by valency and structure, to cover both the compound as shown
and its N-hydroxy (
i.e., N-OH) and N-alkoxy
(i.e., N-OR, wherein R is substituted or unsubstituted C
1-C
6 alkyl, C
1-C
6 alkenyl, C
1-C
6 alkynyl, 3-14-membered carbocycle or 3-14-membered heterocycle) derivatives.
[0235] In the present specification, the structural formula of the compound represents a
certain isomer for convenience in some cases, but the present disclosure includes
all isomers, such as geometrical isomers, optical isomers based on an asymmetrical
carbon, stereoisomers, tautomers, and the like, it being understood that not all isomers
may have the same level of activity. In addition, a crystal polymorphism may be present
for the compounds represented by the formula. It is noted that any crystal form, crystal
form mixture, or anhydride or hydrate thereof is included in the scope of the present
disclosure.
[0236] "Isomerism" means compounds that have identical molecular formulae but differ in
the sequence of bonding of their atoms or in the arrangement of their atoms in space.
Isomers that differ in the arrangement of their atoms in space are termed "stereoisomers."
Stereoisomers that are not mirror images of one another are termed "diastereoisomers,"
and stereoisomers that are non-superimposable mirror images of each other are termed
"enantiomers" or sometimes optical isomers. A mixture containing equal amounts of
individual enantiomeric forms of opposite chirality is termed a "racemic mixture."
[0237] A carbon atom bonded to four nonidentical substituents is termed a "chiral center."
[0238] "Chiral isomer" means a compound with at least one chiral center. Compounds with
more than one chiral center may exist either as an individual diastereomer or as a
mixture of diastereomers, termed "diastereomeric mixture." When one chiral center
is present, a stereoisomer may be characterized by the absolute configuration (R or
S) of that chiral center. Absolute configuration refers to the arrangement in space
of the substituents attached to the chiral center. The substituents attached to the
chiral center under consideration are ranked in accordance with the
Sequence Rule of Cahn, Ingold and Prelog. (
Cahn et al., Angew. Chem. Inter. Edit. 1966, 5, 385; errata 511;
Cahn et al., Angew. Chem. 1966, 78, 413;
Cahn and Ingold, J. Chem. Soc. 1951 (London), 612;
Cahn et al., Experientia 1956, 12, 81;
Cahn, J. Chem. Educ. 1964, 41, 116).
[0239] "Geometric isomer" means the diastereomers that owe their existence to hindered rotation
about double bonds or a cycloalkyl linker (e.g., 1,3-cylcobutyl). These configurations
are differentiated in their names by the prefixes cis and trans, or Z and E, which
indicate that the groups are on the same or opposite side of the double bond in the
molecule according to the Cahn-Ingold-Prelog rules.
[0240] It is to be understood that the compounds of the present disclosure may be depicted
as different chiral isomers or geometric isomers. It should also be understood that
when compounds have chiral isomeric or geometric isomeric forms, all isomeric forms
are intended to be included in the scope of the present disclosure, and the naming
of the compounds does not exclude any isomeric forms, it being understood that not
all isomers may have the same level of activity.
[0241] Furthermore, the structures and other compounds discussed in this disclosure include
all atropic isomers thereof, it being understood that not all atropic isomers may
have the same level of activity. "Atropic isomers" are a type of stereoisomer in which
the atoms of two isomers are arranged differently in space. Atropic isomers owe their
existence to a restricted rotation caused by hindrance of rotation of large groups
about a central bond. Such atropic isomers typically exist as a mixture, however as
a result of recent advances in chromatography techniques, it has been possible to
separate mixtures of two atropic isomers in select cases.
[0242] "Tautomer" is one of two or more structural isomers that exist in equilibrium and
is readily converted from one isomeric form to another. This conversion results in
the formal migration of a hydrogen atom accompanied by a switch of adjacent conjugated
double bonds. Tautomers exist as a mixture of a tautomeric set in solution. In solutions
where tautomerization is possible, a chemical equilibrium of the tautomers will be
reached. The exact ratio of the tautomers depends on several factors, including temperature,
solvent and pH. The concept of tautomers that are interconvertable by tautomerizations
is called tautomerism.
[0243] Of the various types of tautomerism that are possible, two are commonly observed.
In keto-enol tautomerism a simultaneous shift of electrons and a hydrogen atom occurs.
Ring-chain tautomerism arises as a result of the aldehyde group (-CHO) in a sugar
chain molecule reacting with one of the hydroxy groups (-OH) in the same molecule
to give it a cyclic (ring-shaped) form as exhibited by glucose.
[0244] Common tautomeric pairs are: ketone-enol, amide-nitrile, lactam-lactim, amide-imidic
acid tautomerism in heterocyclic rings (e.g., in nucleobases such as guanine, thymine
and cytosine), imine-enamine and enamine-enamine. Examples of lactam-lactim tautomerism
are as shown below.

[0245] It is to be understood that the compounds of the present disclosure may be depicted
as different tautomers. It should also be understood that when compounds have tautomeric
forms, all tautomeric forms are intended to be included in the scope of the present
disclosure, and the naming of the compounds does not exclude any tautomer form. It
will be understood that certain tautomers may have a higher level of activity than
others.
[0246] The term "crystal polymorphs", "polymorphs" or "crystal forms" means crystal structures
in which a compound (or a salt or solvate thereof) can crystallize in different crystal
packing arrangements, all of which have the same elemental composition. Different
crystal forms usually have different X-ray diffraction patterns, infrared spectral,
melting points, density hardness, crystal shape, optical and electrical properties,
stability and solubility. Recrystallization solvent, rate of crystallization, storage
temperature, and other factors may cause one crystal form to dominate. Crystal polymorphs
of the compounds can be prepared by crystallization under different conditions.
[0247] The compounds of any Formula described herein include the compounds themselves, as
well as their salts, and their solvates, if applicable. A salt, for example, can be
formed between an anion and a positively charged group (e.g., amino) on a substituted
benzene compound. Suitable anions include chloride, bromide, iodide, sulfate, bisulfate,
sulfamate, nitrate, phosphate, citrate, methanesulfonate, trifluoroacetate, glutamate,
glucuronate, glutarate, malate, maleate, succinate, fumarate, tartrate, tosylate,
salicylate, lactate, naphthalenesulfonate, and acetate (e.g., trifluoroacetate). The
term "pharmaceutically acceptable anion" refers to an anion suitable for forming a
pharmaceutically acceptable salt. Likewise, a salt can also be formed between a cation
and a negatively charged group (e.g., carboxylate) on a substituted benzene compound.
Suitable cations include sodium ion, potassium ion, magnesium ion, calcium ion, and
an ammonium cation such as tetramethylammonium ion. The substituted benzene compounds
also include those salts containing quaternary nitrogen atoms.
[0248] Additionally, the compounds of the present disclosure, for example, the salts of
the compounds, can exist in either hydrated or unhydrated (the anhydrous) form or
as solvates with other solvent molecules. Nonlimiting examples of hydrates include
monohydrates, dihydrates, etc. Nonlimiting examples of solvates include ethanol solvates,
acetone solvates, etc.
[0249] "Solvate" means solvent addition forms that contain either stoichiometric or non-stoichiometric
amounts of solvent. Some compounds have a tendency to trap a fixed molar ratio of
solvent molecules in the crystalline solid state, thus forming a solvate. If the solvent
is water the solvate formed is a hydrate; and if the solvent is alcohol, the solvate
formed is an alcoholate. Hydrates are formed by the combination of one or more molecules
of water with one molecule of the substance in which the water retains its molecular
state as H
2O.
[0250] As used herein, the term "analog" refers to a chemical compound that is structurally
similar to another but differs slightly in composition (as in the replacement of one
atom by an atom of a different element or in the presence of a particular functional
group, or the replacement of one functional group by another functional group). Thus,
an analog is a compound that is similar or comparable in function and appearance,
but not in structure or origin to the reference compound.
[0251] As defined herein, the term "derivative" refers to compounds that have a common core
structure, and are substituted with various groups as described herein. In some embodiments,
all of the compounds represented by Formula (II) are substituted bi-heterocyclic compounds,
and have Formula (II) as a common core.
[0252] The term "bioisostere" refers to a compound resulting from the exchange of an atom
or of a group of atoms with another, broadly similar, atom or group of atoms. The
objective of a bioisosteric replacement is to create a new compound with similar biological

[0255] The present disclosure provides methods for the synthesis of the compounds of any
of the Formulae described herein. The present disclosure also provides detailed methods
for the synthesis of various disclosed compounds of the present disclosure according
to the following schemes as well as those shown in the Examples.
[0256] Throughout the description, where compositions are described as having, including,
or comprising specific components, it is contemplated that compositions also consist
essentially of, or consist of, the recited components. Similarly, where methods or
processes are described as having, including, or comprising specific process steps,
the processes also consist essentially of, or consist of, the recited processing steps.
Further, it should be understood that the order of steps or order for performing certain
actions is immaterial so long as the invention remains operable. Moreover, two or
more steps or actions can be conducted simultaneously.
[0257] The synthetic processes of the disclosure can tolerate a wide variety of functional
groups, therefore various substituted starting materials can be used. The processes
generally provide the desired final compound at or near the end of the overall process,
although it may be desirable in certain instances to further convert the compound
to a pharmaceutically acceptable salt thereof.
[0258] Compounds of the present disclosure can be prepared in a variety of ways using commercially
available starting materials, compounds known in the literature, or from readily prepared
intermediates, by employing standard synthetic methods and procedures either known
to those skilled in the art, or which will be apparent to the skilled artisan in light
of the teachings herein. Standard synthetic methods and procedures for the preparation
of organic molecules and functional group transformations and manipulations can be
obtained from the relevant scientific literature or from standard textbooks in the
field. Although not limited to any one or several sources, classic texts such as

A4 or a like reagent is combined in an organic solvent (
e.g., methanol) with an enamineodiketone (
e.g., B4) in the presence of an acid (
e.g., acetic acid) to yield a substituted aryl or heteroaryl intermediate
C4 via a cyclocondensation reaction.
[0269] A person of ordinary skill in the art will recognize that in the above schemes the
order of many of the steps are interchangeable.
[0270] Compounds of the present disclosure inhibit the histone methyltransferase activity
of G9a, also known as KMTIC (lysine methyltransferase 1C) or EHMT2 (euchromatic histone

provides methods for treating conditions and diseases the course of which can be influenced
by modulating the methylation status of histones or other proteins, wherein said methylation
status is mediated at least in part by the activity of EHMT2. Modulation of the methylation
status of histones can in turn influence the level of expression of target genes activated
by methylation, and/or target genes suppressed by methylation. The method includes
administering to a subject in need of such treatment, a therapeutically effective

[0278] In some embodiments, the EHMT2-mediated disorder is a hematological disorder.
[0279] The compound(s) of the present disclosure inhibit the histone methyltransferase activity
of EHMT2 or a mutant thereof and, accordingly, the present disclosure also provides
methods for treating conditions and diseases the course of which can be influenced
by modulating the methylation status of histones or other proteins, wherein said methylation
status is mediated at least in part by the activity of EHMT2. In one aspect of the
disclosure, certain compounds disclosed herein are candidates for treating, or preventing
certain conditions, diseases, and disorders. Modulation of the methylation status
of histones can in turn influence the level of expression of target genes activated
by methylation, and/or target genes suppressed by methylation. The method includes
administering to a subject in need of such treatment, a therapeutically effective
amount of a compound of the present disclosure.
[0280] As used herein, a "subject" is interchangeable with a "subject in need thereof",
both of which refer to a subject having a disorder in which EHMT2-mediated protein
methylation plays a part, or a subject having an increased risk of developing such
disorder relative to the population at large. A "subject" includes a mammal. The mammal
can be
e.g., a human or appropriate non-human mammal, such as primate, mouse, rat, dog, cat, cow,
horse, goat, camel, sheep or a pig. The subject can also be a bird or fowl. In one
embodiment, the mammal is a human. A subject in need thereof can be one who has been
previously diagnosed or identified as having cancer or a precancerous condition. A
subject in need thereof can also be one who has (e.g., is suffering from) cancer or
a precancerous condition. Alternatively, a subject in need thereof can be one who
has an increased risk of developing such disorder relative to the population at large
(
i.e., a subject who is predisposed to developing such disorder relative to the population
at large). A subject in need thereof can have a precancerous condition. A subject
in need thereof can have refractory or resistant cancer (i.e., cancer that does not
respond or has not yet responded to treatment). The subject may be resistant at start
of treatment or may become resistant during treatment. In some embodiments, the subject
in need thereof has cancer recurrence following remission on most recent therapy.
In some embodiments, the subject in need thereof received and failed all known effective
therapies for cancer treatment. In some embodiments, the subject in need thereof received
at least one prior therapy. In a preferred embodiment, the subject has cancer or a
cancerous condition. In some embodiments, the cancer is leukemia, prostate carcinoma,
hepatocellular carcinoma, and lung cancer.
[0281] As used herein, "candidate compound" refers to a compound of the present disclosure,
or a pharmaceutically acceptable salt, polymorph or solvate thereof, that has been
or will be tested in one or more
in vitro or
in vivo biological assays, in order to determine if that compound is likely to elicit a desired
biological or medical response in a cell, tissue, system, animal or human that is
being sought by a researcher or clinician. A candidate compound is a compound of the
present disclosure, or a pharmaceutically acceptable salt, polymorph or solvate thereof.
The biological or medical response can be the treatment of cancer. The biological
or medical response can be treatment or prevention of a cell proliferative disorder.
The biological response or effect can also include a change in cell proliferation
or growth that occurs
in vitro or in an animal model, as well as other biological changes that are observable
in vitro. In vitro or
in vivo biological assays can include, but are not limited to, enzymatic activity assays,
electrophoretic mobility shift assays, reporter gene assays,
in vitro cell viability assays, and the assays described herein.
[0282] In some embodiments, an
in vitro biological assay that can be used includes the steps of (1) mixing a histone substrate
(
e.
g., an isolated histone sample or an isolated histone peptide representative of human
histone H3 residues 1-15) with recombinant EHMT2 enzymes; (2) adding a compound of
the disclosure to this mixture; (3) adding non-radioactive and
3H-labeled S-Adenosyl methionine (SAM) to start the reaction; (4) adding excessive
amount of non-radioactive SAM to stop the reaction; (4) washing off the free non-incorporated
3H-SAM; and (5) detecting the quantity of
3H-labeled histone substrate by any methods known in the art

a secondary antibody (
e.
g. an antibody conjugated to an infrared dye); (6) detecting the quantity of bound
antibody by any methods known in the art (
e.g., by a Licor Odyssey Infrared Scanner).
[0284] As used herein, "treating" or "treat" describes the management and care of a patient
for the purpose of combating a disease, condition, or disorder and includes the administration
of a compound of the present disclosure, or a pharmaceutically acceptable salt, polymorph
or solvate thereof, to alleviate the symptoms or complications of a disease, condition
or disorder, or to eliminate the disease, condition or disorder. The term "treat"
can also include treatment of a cell
in vitro or an animal model.
[0285] A compound of the present disclosure, or a pharmaceutically acceptable salt, polymorph
or solvate thereof, can or may also be used to prevent a relevant disease, condition
or disorder, or used to identify suitable candidates for such purposes. As used herein,
"preventing," "prevent," or "protecting against" describes reducing or eliminating
the onset of the symptoms or complications of such disease, condition or disorder.
[0286] One skilled in the art may refer to general reference texts for detailed descriptions
of known techniques discussed herein or equivalent techniques. These texts include

Sciences, Mack Publishing Co., Easton, PA, 18th edition (1990). These texts can, of course, also be referred to in making or using an aspect of
the disclosure.
[0287] As used herein, "combination therapy" or "co-therapy" includes the administration
of a compound of the present disclosure, or a pharmaceutically acceptable salt, polymorph
or solvate thereof, and at least a second agent as part of a specific treatment regimen
intended to provide the beneficial effect from the co-action of these therapeutic
agents. The beneficial effect of the combination includes, but is not limited to,
pharmacokinetic or pharmacodynamic co-action resulting from the combination of therapeutic
agents.
[0288] The present disclosure also provides pharmaceutical compositions comprising a compound
of any of the Formulae described herein in combination with at least one pharmaceutically
acceptable excipient or carrier.
[0289] A "pharmaceutical composition" is a formulation containing the compounds of the present
disclosure in a form suitable for administration to a subject. In one embodiment,
the pharmaceutical composition is in bulk or in unit dosage form. The unit dosage
form is any of a variety of forms, including, for example, a capsule, an IV bag, a
tablet, a single pump on an aerosol inhaler or a vial. The quantity of active ingredient
(
e.
g., a formulation of the disclosed compound or salt, hydrate, solvate or isomer thereof)
in a unit dose of composition is an effective amount and is varied according to the
particular treatment involved. One skilled in the art will appreciate that it is sometimes
necessary to make routine variations to the dosage depending on the age and condition
of the patient. The dosage will also depend on the route of administration. A variety
of routes are contemplated, including oral, pulmonary, rectal, parenteral, transdermal,
subcutaneous, intravenous, intramuscular, intraperitoneal, inhalational, buccal, sublingual,
intrapleural, intrathecal, intranasal, and the like. Dosage forms for the topical
or transdermal administration of a compound of this disclosure include powders, sprays,
ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. In one
embodiment, the active compound is mixed under sterile conditions with a pharmaceutically
acceptable carrier, and with any preservatives, buffers, or propellants that are required.
[0290] As used herein, the phrase "pharmaceutically acceptable" refers to those compounds,
anions, cations, materials, compositions, carriers, and/or dosage forms which are,
within the scope of sound medical judgment, suitable for use in contact with the tissues
of human beings and animals without excessive toxicity, irritation, allergic response,
or other problem or complication, commensurate with a reasonable benefit/risk ratio.
[0291] "Pharmaceutically acceptable excipient" means an excipient that is useful in preparing
a pharmaceutical composition that is generally safe, non-toxic and neither biologically
nor otherwise undesirable, and includes excipient that is acceptable for veterinary
use as well as human pharmaceutical use. A "pharmaceutically acceptable excipient"
as used in the specification and claims includes both one and more than one such excipient.
[0292] A pharmaceutical composition of the disclosure is formulated to be compatible with
its intended route of administration. Examples of routes of administration include
parenteral,
e.
g., intravenous, intradermal, subcutaneous, oral (
e.
g., inhalation), transdermal (topical), and transmucosal administration. Solutions
or suspensions used for parenteral, intradermal, or subcutaneous application can include
the following components: a sterile diluent such as water for injection, saline solution,
fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents;
antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such
as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic
acid; buffers such as acetates, citrates or phosphates, and agents for the adjustment
of tonicity such as sodium chloride or dextrose. The pH can be adjusted with acids
or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation
can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass
or plastic.
[0293] A compound or pharmaceutical composition of the disclosure can be administered to
a subject in many of the well-known methods currently used for chemotherapeutic treatment.
In some embodiments, for treatment of cancers, a compound of the disclosure may be
injected directly into tumors, injected into the blood stream or body cavities or
taken orally or applied through the skin with patches. The dose chosen should be sufficient
to constitute effective treatment but not so high as to cause unacceptable side effects.
The state of the disease condition (
e.
g., cancer, precancer, and the like) and the health of the patient should preferably
be closely monitored during and for a reasonable period after treatment.
[0294] The term "therapeutically effective amount", as used herein, refers to an amount
of a pharmaceutical agent to treat, ameliorate, or prevent an identified disease or
condition, or to exhibit a detectable therapeutic or inhibitory effect. The effect
can be detected by any assay method known in the art. The precise effective amount
for a subject will depend upon the subject's body weight, size, and health; the nature
and extent of the condition; and the therapeutic or combination of therapeutics selected
for administration. Therapeutically effective amounts for a given situation can be
determined by routine experimentation that is within the skill and judgment of the
clinician. In a preferred aspect, the disease or condition to be treated is cancer.
In another aspect, the disease or condition to be treated is a cell proliferative
disorder.
[0295] For any compound, the therapeutically effective amount can be estimated initially
either in cell culture assays,
e.
g., of neoplastic cells, or in animal models, usually rats, mice, rabbits, dogs, or
pigs. The animal model may also be used to determine the appropriate concentration
range and route of administration. Such information can then be used to determine
useful doses and routes for administration in humans. Therapeutic/prophylactic efficacy
and toxicity may be determined by standard pharmaceutical procedures in cell cultures
or experimental animals,
e.
g., ED
50 (the dose therapeutically effective in 50% of the population) and LD
50 (the dose lethal to 50% of the population). The dose ratio between toxic and therapeutic
effects is the therapeutic index, and it can be expressed as the ratio, LD
50/ED
50. Pharmaceutical compositions that exhibit large therapeutic indices are preferred.
The dosage may vary within this range depending upon the dosage form employed, sensitivity
of the patient, and the route of administration.
[0296] Dosage and administration are adjusted to provide sufficient levels of the active
agent(s) or to maintain the desired effect. Factors which may be taken into account
include the severity of the disease state, general health of the subject, age, weight,
and gender of the subject, diet, time and frequency of administration, drug combination(s),
reaction sensitivities, and tolerance/response to therapy. Long-acting pharmaceutical
compositions may be administered every 3 to 4 days, every week, or once every two
weeks depending on half-life and clearance rate of the particular formulation.
[0297] The pharmaceutical compositions containing active compounds of the present disclosure
may be manufactured in a manner that is generally known,
e.
g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating,
emulsifying, encapsulating, entrapping, or lyophilizing processes. Pharmaceutical
compositions may be formulated in a conventional manner using one or more pharmaceutically
acceptable carriers comprising excipients and/or auxiliaries that facilitate processing
of the active compounds into preparations that can be used pharmaceutically. Of course,
the appropriate formulation is dependent upon the route of administration chosen.
[0298] Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions
(where water soluble) or dispersions and sterile powders for the extemporaneous preparation
of sterile injectable solutions or dispersion. For intravenous administration, suitable
carriers include physiological saline, bacteriostatic water, Cremophor EL
™ (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition
must be sterile and should be fluid to the extent that easy syringeability exists.
It must be stable under the conditions of manufacture and storage and must be preserved
against the contaminating action of microorganisms such as bacteria and fungi. The
carrier can be a solvent or dispersion medium containing, for example, water, ethanol,
polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and
the like), and suitable mixtures thereof. The proper fluidity can be maintained, for
example, by the use of a coating such as lecithin, by the maintenance of the required
particle size in the case of dispersion and by the use of surfactants. Prevention
of the action of microorganisms can be achieved by various antibacterial and antifungal
agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and
the like. In many cases, it will be preferable to include isotonic agents, for example,
sugars, polyalcohols such as mannitol and sorbitol, and sodium chloride in the composition.
Prolonged absorption of the injectable compositions can be brought about by including
in the composition an agent which delays absorption, for example, aluminum monostearate
and gelatin.
[0299] Sterile injectable solutions can be prepared by incorporating the active compound
in the required amount in an appropriate solvent with one or a combination of ingredients
enumerated above, as required, followed by filtered sterilization. Generally, dispersions
are prepared by incorporating the active compound into a sterile vehicle that contains
a basic dispersion medium and the required other ingredients from those enumerated
above. In the case of sterile powders for the preparation of sterile injectable solutions,
methods of preparation are vacuum drying and freeze-drying that yields a powder of
the active ingredient plus any additional desired ingredient from a previously sterile-filtered
solution thereof.
[0300] Oral compositions generally include an inert diluent or an edible pharmaceutically
acceptable carrier. They can be enclosed in gelatin capsules or compressed into tablets.
For the purpose of oral therapeutic administration, the active compound can be incorporated
with excipients and used in the form of tablets, troches, or capsules. Oral compositions
can also be prepared using a fluid carrier for use as a mouthwash, wherein the compound
in the fluid carrier is applied orally and swished and expectorated or swallowed.
Pharmaceutically compatible binding agents, and/or adjuvant materials can be included
as part of the composition. The tablets, pills, capsules, troches and the like can
contain any of the following ingredients, or compounds of a similar nature: a binder
such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as
starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn
starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal
silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent
such as peppermint, methyl salicylate, or orange flavoring.
[0301] For administration by inhalation, the compounds are delivered in the form of an aerosol
spray from pressured container or dispenser, which contains a suitable propellant,
e.
g., a gas such as carbon dioxide, or a nebulizer.
[0302] Systemic administration can also be by transmucosal or transdermal means. For transmucosal
or transdermal administration, penetrants appropriate to the barrier to be permeated
are used in the formulation. Such penetrants are generally known in the art, and include,
for example, for transmucosal administration, detergents, bile salts, and fusidic
acid derivatives. Transmucosal administration can be accomplished through the use
of nasal sprays or suppositories. For transdermal administration, the active compounds
are formulated into ointments, salves, gels, or creams as generally known in the art.
[0303] The active compounds can be prepared with pharmaceutically acceptable carriers that
will protect the compound against rapid elimination from the body, such as a controlled
release formulation, including implants and microencapsulated delivery systems. Biodegradable,
biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides,
polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation
of such formulations will be apparent to those skilled in the art. The materials can
also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc.
Liposomal suspensions (including liposomes targeted to infected cells with monoclonal
antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers.
These can be prepared according to methods known to those skilled in the art, for
example, as described in
U.S. Pat. No. 4,522,811.
[0304] It is especially advantageous to formulate oral or parenteral compositions in dosage
unit form for ease of administration and uniformity of dosage. Dosage unit form as
used herein refers to physically discrete units suited as unitary dosages for the
subject to be treated; each unit containing a predetermined quantity of active compound
calculated to produce the desired therapeutic effect in association with the required
pharmaceutical carrier. The specification for the dosage unit forms of the disclosure
are dictated by and directly dependent on the unique characteristics of the active
compound and the particular therapeutic effect to be achieved.
[0305] In therapeutic applications, the dosages of the pharmaceutical compositions used
in accordance with the disclosure vary depending on the agent, the age, weight, and
clinical condition of the recipient patient, and the experience and judgment of the
clinician or practitioner administering the therapy, among other factors affecting
the selected dosage. Generally, the dose should be sufficient to result in slowing,
and preferably regressing, the growth of the tumors and also preferably causing complete
regression of the cancer. Dosages can range from about 0.01 mg/kg per day to about
5000 mg/kg per day. In preferred aspects, dosages can range from about 1 mg/kg per
day to about 1000 mg/kg per day. In an aspect, the dose will be in the range of about
0.1 mg/day to about 50 g/day; about 0.1 mg/day to about 25 g/day; about 0.1 mg/day
to about 10 g/day; about 0.1 mg to about 3 g/day; or about 0.1 mg to about 1 g/day,
in single, divided, or continuous doses (which dose may be adjusted for the patient's
weight in kg, body surface area in m
2, and age in years). An effective amount of a pharmaceutical agent is that which provides
an objectively identifiable improvement as noted by the clinician or other qualified
observer. In some embodiments, regression of a tumor in a patient may be measured
with reference to the diameter of a tumor. Decrease in the diameter of a tumor indicates
regression. Regression is also indicated by failure of tumors to reoccur after treatment
has stopped. As used herein, the term "dosage effective manner" refers to amount of
an active compound to produce the desired biological effect in a subject or cell.
[0306] The pharmaceutical compositions can be included in a container, pack, or dispenser
together with instructions for administration.
[0307] The compounds of the present disclosure are capable of further forming salts. All
of these forms are also contemplated within the scope of the claimed disclosure.
[0308] As used herein, "pharmaceutically acceptable salts" refer to derivatives of the compounds
of the present disclosure wherein the parent compound is modified by making acid or
base salts thereof. Examples of pharmaceutically acceptable salts include, but are
not limited to, mineral or organic acid salts of basic residues such as amines, alkali
or organic salts of acidic residues such as carboxylic acids, and the like. The pharmaceutically
acceptable salts include the conventional non-toxic salts or the quaternary ammonium
salts of the parent compound formed, for example, from non-toxic inorganic or organic
acids. In some embodiments, such conventional non-toxic salts include, but are not
limited to, those derived from inorganic and organic acids selected from 2-acetoxybenzoic,
2-hydroxyethane sulfonic, acetic, ascorbic, benzene sulfonic, benzoic, bicarbonic,
carbonic, citric, edetic, ethane disulfonic, 1,2-ethane sulfonic, fumaric, glucoheptonic,

[0309] Other examples of pharmaceutically acceptable salts include hexanoic acid, cyclopentane
propionic acid, pyruvic acid, malonic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic
acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic
acid, camphorsulfonic acid, 4-methylbicyclo-[2.2.2]-oct-2-ene-1-carboxylic acid, 3-phenylpropionic
acid, trimethylacetic acid, tertiary butylacetic acid, muconic acid, and the like.
The present disclosure also encompasses salts formed when an acidic proton present
in the parent compound either is replaced by a metal ion,
e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with
an organic base such as ethanolamine, diethanolamine, triethanolamine, tromethamine,
N-methylglucamine, and the like. In the salt form, it is understood that the ratio
of the compound to the cation or anion of the salt can be 1:1, or any ration other
than 1:1, e.g., 3:1, 2:1, 1:2, or 1:3.
[0310] It should be understood that all references to pharmaceutically acceptable salts
include solvent addition forms (solvates) or crystal forms (polymorphs) as defined
herein, of the same salt.
[0311] The compounds of the present disclosure can also be prepared as esters, for example,
pharmaceutically acceptable esters. In some embodiments, a carboxylic acid function
group in a compound can be converted to its corresponding ester,
e.g., a methyl, ethyl or other ester. Also, an alcohol group in a compound can be converted
to its corresponding ester,
e.
g., acetate, propionate or other ester.
[0312] The compounds, or pharmaceutically acceptable salts thereof, are administered orally,
nasally, transdermally, pulmonary, inhalationally, buccally, sublingually, intraperitoneally,
subcutaneously, intramuscularly, intravenously, rectally, intrapleurally, intrathecally
and parenterally. In one embodiment, the compound is administered orally. One skilled
in the art will recognize the advantages of certain routes of administration.
[0313] The dosage regimen utilizing the compounds is selected in accordance with a variety
of factors including type, species, age, weight, sex and medical condition of the
patient; the severity of the condition to be treated; the route of administration;
the renal and hepatic function of the patient; and the particular compound or salt
thereof employed. An ordinarily skilled physician or veterinarian can readily determine
and prescribe the effective amount of the drug required to prevent, counter, or arrest
the progress of the condition.
[0314] Techniques for formulation and administration of the disclosed compounds of the disclosure
can be found in
Remington: the Science and Practice of Pharmacy, 19th edition, Mack Publishing Co.,
Easton, PA (1995). In an embodiment, the compounds described herein, and the pharmaceutically acceptable

Example 20: Bioactivity Assays
MATERIALS AND EQUIPMENT:
[0491] Recombinant purified human EHMT2 913-1193 (55 µM) synthesized by Viva was used for
all experiments. Biotinylated histone peptides were synthesized by Biopeptide and
HPLC-purified to > 95% purity. Streptavidin Flashplates and seals were purchased from
PerkinElmer and 384 Well V-bottom Polypropylene Plates were from Greiner.
3H-labeled
S-adenosylmethionine (
3H-SAM) was obtained from American Radiolabeled Chemicals with a specific activity
of 80 Ci/mmol. Unlabeled SAM and S-adenosylhomocysteine (SAH) were obtained from American
Radiolabeled Chemicals and Sigma-Aldrich respectively. Flashplates were washed in
a Biotek ELx-405 with 0.1% Tween. 384-well Flashplates and 96-well filter binding
plates were read on a TopCount microplate reader (PerkinElmer). Compound serial dilutions
were performed on a Freedom EVO (Tecan) and spotted into assay plates using a Thermo
Scientific Matrix PlateMate (Thermo Scientific). Reagent cocktails were added by Multidrop
Combi (Thermo Scientific).
[0492] MDA-MB-231 cell line was purchased from ATCC (Manassas, VA, USA). RPMI/Glutamax medium,
Penicillin-Streptomycin, Heat Inactivated Fetal Bovine Serum, and D-PBS were purchased
from Life Technologies (Grand Island, NY, USA). Odyssey blocking buffer, 800CW goat
anti-mouse IgG (H+L) antibody, and Licor Odyssey Infrared Scanner were purchased from
Licor Biosciences, Lincoln, NE, USA. H3K9me2 mouse monoclonal antibody (Cat #1220)
was purchased from Abeam (Cambridge, MA, USA). 16% Paraformaldehyde was purchased
from Electron Microscopy Sciences, Hatfield, PA, USA).MDA-MB-231 cells were maintained
in complete growth medium (RPMI supplemented with 10% v/v heat inactivated fetal bovine
serum) and cultured at 37 °C under 5% CO
2. UNC0638 was purchased from Sigma-Aldrich (St. Louis, MO, USA).
[0493] Various
In vitro or
in vivo biological assays are may be suitable for detecting the effect of the compounds of
the present disclosure. These i
n vitro or
in vivo biological assays can include, but are not limited to, enzymatic activity assays,
electrophoretic mobility shift assays, reporter gene assays,
in vitro cell viability assays, and the assays described herein.
[0494] General Procedure for EHMT2 Enzyme Assay on Histone Peptide Substrate. 10-point curves of test compounds were made on a Freedom EVO (Tecan) using serial
3-fold dilutions in DMSO, beginning at 2.5 mM (final top concentration of compound
was 50 µM and the DMSO was 2%). A 1 µL aliquot of the inhibitor dilution series was
spotted in a polypropylene 384-well V-bottom plate (Greiner) using a Thermo Scientific
Matrix PlateMate (Thermo Scientific). The 100% inhibition control consisted of 1 mM
final concentration of the product inhibitor S-adenosylhomocysteine (SAH, Sigma-Aldrich).
Compounds were incubated for 30 minutes with 40 µL, per well of 0.031 nM EHMT2 (recombinant
purified human EHMT2 913-1193, Viva) in 1X assay buffer (20 mM Bicine [pH 7.5], 0.002%
Tween 20, 0.005% Bovine Skin Gelatin and 1 mM TCEP). 10 µL per well of substrate mix
comprising assay buffer,
3H-SAM (
3H-labeled
S-adenosylmethionine, American Radiolabeled Chemicals, specific activity of 80 Ci/mmol),
unlabeled SAM (American Radiolabeled Chemicals), and peptide representing histone
H3 residues 1-15 containing C-terminal biotin (appended to a C-terminal amide-capped
lysine, synthesized by Biopeptide and HPLC-purified to greater than 95% purity) were
added to initiate the reaction (both substrates were present in the final reaction
mixture at their respective K
m values, an assay format referred to as "balanced conditions"). Reactions were incubated
for 60 minutes at room temperature and quenched with 10 µL per well of 400 µM unlabeled
SAM, then transferred to a 384-well streptavidin Flashplate (PerkinElmer) and washed
in a Biotek ELx-405 well washer with 0.1% Tween after 60 minutes. 384-well Flashplates
were read on a TopCount microplate reader (PerkinElmer).
[0495] General Procedure for MDA-MB-231 HEK9me2 in-cell Western Assay. Compound (100 nL) was added directly to 384-well cell plate. MDA-MB-231 cells (ATCC)
were seeded in assay medium (RPMI/Glutamax supplemented with 10% v/v heat inactivated
fetal bovine serum and 1% Penicillin/Streptomycin, Life Technologies) at a concentration
of 3,000 cells per well to a Poly-D-Lysine coated 384-well cell culture plate with
50 µL per well. Plates were incubated at 37°C, 5% CO
2 for 48 hours (BD Biosciences 356697). Plates were incubated at room temperature for
30 minutes and then incubated at 37°C, 5% CO
2 for additional 48 hours. After the incubation, 50 µL per well of 8% paraformaldehyde
(Electron Microscopy Sciences) in PBS was added to the plates and incubated at room
temperature for 20 minutes. Plates were transferred to a Biotek 406 plate washer and
washed 2 times with 100 µL per well of wash buffer (1X PBS containing 0.3% Triton
X-100 (v/v)). Next, 60 µL per well of Odyssey blocking buffer (Licor Biosciences)
was added to each plate and incubated for 1 hour at room temperature. Blocking buffer
was removed and 20 µL of monoclonal primary antibody α-H3K9me2 (Abcam) diluted 1:800
in Odyssey buffer with 0.1% Tween 20 (v/v) were added and plates were incubated overnight
(16 hours) at 4 °C. Plates were washed 5 times with 100 µL per well of wash buffer.
Next 20 µL per well of secondary antibody was added (1:500 800CW donkey anti-mouse
IgG (H+L) antibody (Licor Biosciences), 1:1000 DRAQ5 (Cell Signaling Technology) in
Odyssey buffer with 0.1% Tween 20 (v/v)) and incubated for 1 hour at room temperature.
The plates were washed 5 times with 100 µL per well wash buffer then 2 times with
100 µL per well of water. Plates were allowed to dry at room temperature then imaged
on a Licor Odyssey Infrared Scanner (Licor Biosciences) which measured integrated
intensity at 700 nm and 800 nm wavelengths. Both 700 and 800 channels were scanned.
[0496] % Inhibition Calculation. First, the ratio for each well was determined by:

[0497] Each plate included fourteen control wells of DMSO only treatment (Minimum Inhibition)
as well as fourteen control wells (background wells) for maximum inhibition treated
with control compound UNC0638 (Background wells).
[0498] The average of the ratio values for each well was calculated and used to determine
the percent inhibition for each test well in the plate. Control compound was serially
diluted three-fold in DMSO for a total of 10 test concentrations beginning at 1 µM.
Percent inhibition was calculated as:

[0499] IC
50 curves were generated using triplicate wells per concentration of compound. The IC
50 is the concentration of compound at which measured methylation is inhibited by 50%
as interpolated from the dose response curves. IC
50 values were calculated using a non-linear regression (variable slope-four parameter
fit model) with by the following formula:

where
Top is fixed at 100% and
Bottom is fixed to 0%, [I] = concentration of inhibitor,
IC50 = half maximal inhibitory concentration and
n = Hill Slope.
[0500] The IC
50 values are listed in Table 3 below ("A" means IC
50 <100 nM; "B" means IC
50 ranging between 100 nM and 1 µM; "C" means IC
50 ranging between >1 µM and 10 µM; "D" means IC
50>10 µM; "-" or "ND" means not determined).
